Private unmanaged overlay L2 networks for CloudStack using KVM and VXLAN

On September 5, 2018, we published the first release of the new CloudStack extension, which is designed to automatically deploy unmanaged private LANs for accounts and CloudStack projects. The extension is only for use with clouds running under the KVM hypervisor. After installation, each virtual machine in the account receives an additional VirtIO network card, which belongs to a private network accessible only to machines created within the account.

The extension also allows you to allocate additional private networks and merge multiple accounts into a single local network. Private networks are organized through VXLAN overlay networks, working with multicasting groups. The extension does not have limitations on the use of a specific version of CloudStack and can be used in conjunction with various CloudStack zones – basic and advanced without restrictions.

This extension is especially interesting for CloudStack installations that use Basic Zones or Advanced Zones with Shared Networks, allowing cloud administrators to effortlessly begin to provide users with a private backbone network that is fully configurable by the user in their own way.

The extension has been successfully deployed to the public cloud and the beta mode of operation is under way.

The software product is released under a closed license and is not planned for publication in opensource mode. If you are interested in this extension, please contact us by e-mail cloudstack (at) bitworks.software to discuss the details and the possibility of implementation in your cloud. Before implementation, we can perform additional customization for customer requirements, subscription-based support is provided.
